BACKGROUND OF THE DISCLOSURE Field of the Invention

This invention relates generally to a system and method for broadcastresponse.

Description of the Related Art

Broadcast transmissions often include ancillary signals such asbackground music or reading services for the blind along with a maincarrier signal. The Radio Data System (“RDS”) standard is aninternational standard that defines a basic FM subcarrier digital codingand transmission system. The most current and widely used datatransmission standard in the United States is the Radio Broadcast DataSystems (“RBDS”) standard. The RBDS standard defines how to implementthe RDS standard in North America.

The RBDS standard, published by the National Radio Systems Committee andsponsored by the Electronic Industries Association and the NationalAssociation of Broadcasters, describes a system for broadcasting avariety of program-related information on a subcarrier of a standard FMbroadcast channel. It was designed to allow stations to send informationsuch as call letters, station format, traffic alerts and text messagesto compatible radios.

RDS encoders generate what is known as a “subcarrier” that istransmitted along with an FM station broadcast signal and can bedemodulated by special decoders. The RDS uses a subcarrier frequency of57 khz. Commercially available RDS encoders usually accept informationvia either serial or parallel data ports and format the information intothe appropriate RDS block type.

The RDS data signal is a specially encoded data stream containing up to32 repeating “groups” and is transmitted at 1187.5 bits/second. The RDSdata signal does not require inclusion of all potential data groupblocks of both repeating and unique data. Certain embodiments includeusing one of several groups that are designed for data transmissionfunctions.

An RDS data group is composed of 4 blocks, each divided by checkwordsused for error correction. Block 1 is a 16-bit Program Identificationcode (PI) which contains a country symbol, a regional code, and a numberwhich is derived from the transmitting station's call letters. Block 2includes a 4-bit group type code and a 1-bit group version code thatidentifies the type of information the data group contains. This blockalso contains a 1-bit code that identifies the transmitting station asone that broadcasts traffic information, followed by a 5-bit ProgramType (PTY) code which describes the current program or format beingbroadcast by the station (Rock, Oldies, Talk, News, etc.).

Information contained in Blocks 3 and 4 are dependent on the codesincluded in Block 2. Blocks 3 and 4 provide two 16-bit data slots wherespecific information can be sent to the special receiver. For example,RDS Group type 2A uses blocks 3 and 4 to transmit a segmented64-character text message known as RadioText (RT). This appears onRDS-enabled radios as a message that some stations use to identify thesong or program. Other group types use these blocks to identifyalternate frequencies where the same programming can be available,in-house station text messages, or Emergency Alert System (EAS)communication messages. An extensive description of the RDS standard isavailable through the National Association of Broadcasters and theNational Radio Systems Committee.

Broadcasters using the RDS standard can distribute information to alarge number of users. However, the standard does not provide forindividual users to respond to the broadcast information.

DETAILED DESCRIPTION

Although certain preferred embodiments and examples are disclosed below,it will be understood by those of ordinary skill in the art that theinvention extends beyond the specifically disclosed embodiments to otheralternative embodiments and uses of the invention and obviousmodifications and equivalents thereof. Thus, the particular embodimentsdescribed below are not intended to limit the scope of the inventionherein disclosed.

The present patent application hereby incorporates by reference theentirety of the contents of U.S. Provisional Application No. 60/232,333,filed Sep. 13, 2000, titled “SYSTEM AND METHOD FOR ORDERING ANDDELIVERING MEDIA CONTENT,” and U.S. patent application Ser. No.09/953,335, filed Sep. 13, 2001, titled “SYSTEM AND METHOD FOR ORDERINGAND DELIVERING MEDIA CONTENT.”

FIG. 1 illustrates an exemplary high-level overview of a broadcastresponse system. As illustrated, a broadcast data preparation module 102is in communication with a broadcast system 104. The broadcast datapreparation module 102 prepares data for broadcast transmission. In oneembodiment, the prepared data contains information pertaining to themain broadcast signal. For example, data containing the title of a songor name of an artist may be broadcast in concert with a music piece. Adsmay also be identified in a similar fashion. Other informationpertaining to the main broadcast signal may include data such as apurchase price, a purchase location or a unique identifier. The prepareddata, however, is not required to pertain to the main broadcast signal.Commercial advertisements unrelated to the main signal are an example ofbroadcast data that may not directly correspond to the main broadcastsignal.

In one embodiment, the broadcast system 104 transmits the data using asubcarrier signal. For example, the broadcast system 104 may transmitdata in conformance with the RDS standard, the RBDS standard, the DARCstandard, or other appropriate formats. Although many of the embodimentsdisclosed herein specifically refer to the RDS standard, it is to beunderstood other embodiments may use different formats, such as the RBDSstandard, the DARC standard, or other implementations for broadcasting.Further, many of the embodiments disclosed herein specifically refer toradio, but it is to be understood that other broadcast formats such astelevision broadcasts are also within the scope of this disclosure.

A broadcast reception module 106 receives broadcast transmissions fromthe broadcast system 104 and extracts the transmitted data. Theextracted data may then be used, for example, to display informationsuch as the title of the song or name of the artist to a user.

A user response module 108 detects responses by a user. For example, theuser response module 108 may detect a user pressing a button in responseto data transmitted by the broadcast system 104. Other user responsesmay include, for example, tuning into a different broadcast signal,turning a device on or off, adjusting the broadcast signal volume,pressing a touch screen, entering keypad data, issuing instructions byspeaking, or issuing instructions using eye motion commands. In apreferred embodiment, the user initiates an information request for abroadcast program by pressing a button during the broadcast or byrecalling stored data at a later time.

FIG. 1 further illustrates the user response module 108 being incommunication with a data management module 110. In one embodiment, thecommunication occurs over a network 112 such as a wide-area network(WAN). The data management module 110 is also in communication with thebroadcast data preparation module. This allows synchronization of theuser generated responses from the user response module 108 with thebroadcast data generated from the broadcast data preparation module 102.

The high-level overview illustrated in FIG. 1 partitions thefunctionality of the overall system into modules for ease ofexplanation. It is to be understood, however, that one or more modulesmay operate as a single unit. Conversely, a single module may compriseone or more subcomponents that are distributed throughout one or morelocations. Further, the communication between the modules may occur in avariety of ways, such as hardware implementations (e.g., network, serialinterface, parallel interface, or internal bus), softwareimplementations (e.g., database, DDE (Dynamic Data Exchange), functioncall), or a combination of hardware and software. Further, the modulesmay be realized using state machines, microcode, microprocessors,digital signal processors, or any other appropriate digital or analogtechnology.

The following describes an exemplary embodiment wherein a radio stationuses the broadcast system 104. The radio station generates programmingdata in conjunction with the broadcast signal. The radio stationcommunicates the programming data to the broadcast data preparationmodule 102. In this exemplary embodiment, the broadcast data preparationmodule 102 comprises a database that contains entries corresponding tothe programming data. In certain embodiments the data is formatted andsent to a database. In certain embodiments the data is formatted andsent to a database.

The broadcast data preparation module 102 provides a unique identifierfor the programming data to the radio station. The broadcast datapreparation module 102 may also provide additional information about theprogram to the radio station. The radio station broadcasts the uniqueidentifier and any other desired information using the RDS subcarrier. Aradio, using the broadcast data reception module 106, extracts theunique identifier from the RDS subcarrier. When a user presses a buttonindicating that the user desires to obtain additional informationregarding content corresponding to the broadcast, the user responsemodule 108 communicates the unique identifier and a user identifier tothe data management module 110. The data management module 110 looks upthe unique identifier and user identifier in a database, and uses thisinformation to fulfill the order. This presently preferred embodiment isexemplary only, and further details regarding this and other embodimentsare set forth below.

Broadcast Data Preparation

FIG. 2 shows an exemplary overview of a system for preparing data fortransmission over a subcarrier channel The process begins with a contentidentification module 120, which extracts information used to correlatecontent with the unique identifier. This identifying information mayinclude, for example, the title, artist, radio station, program,sponsor, or advertising campaign.

In one embodiment, the content identification module 120 automaticallyextracts content information 124 from a playlist. For example, thecontent identification module 120 may include a radio automation systemthat extracts information about songs or a radio program from thestation playlist. In another embodiment, the content identificationmodule 120 uses a media playback system to automatically extract contentinformation 124 encoded on media, such as the identification codes ortrack numbers on a CD-ROM. Other embodiments of the contentidentification module 120 may provide a user interface for manuallyentering content information 124.

Music radio stations often depend on playlists to ensure consistency andsuccess of the format. Many stations use computer-based playback systemsthat play from hard disc libraries or control CD changers. A compiledplaylist includes information or cue sheets for the songs to be aired,advertisements to be run, or other content to be broadcast. These“automation” systems provide continual logging of functions andactivities and can output the “as played” information in a variety ofways, such as serial data. Data can be taken as an event occurs or canbe read from a text file. Most automated systems can be programmed tosend information out of the serial port or to an IP data packet.

Some stations may route this data through the subcarrier using RDS, thusdisplaying song information in the RadioText or PS (Program ServiceName) groups. Stations may also use this information to feed a “nowplaying” message on Internet web sites.

Even stations that play CDs manually from a paper playlist can providethe information needed. Professional CD players usually have serialports (i.e., RS232, RS485) that can be programmed to transmit CD codeinformation. This code information is similar to the song codes used byinternet-enabled computers to automatically download song informationfrom the website known as CDDB.com for a CD inserted into a CD-ROMplayer. RIAA (Recording Industry Association of America) registered CDscontain registration codes that can be used in combination with thetrack length or number of tracks to identify content. Thus, on a RIAAregistered CD, a song can be identified by the registered code number incombination with the track number. In one embodiment, the broadcasterproviding the service to its listeners assigns an identifier code to thecontent. In another embodiment, an identifier code is provided by aregistering organization or service. In yet another embodiment, RIAA,CDDB or other identifiers are stored in the content database and areused in whole or in part to create an identifier. In another embodiment,RIAA, CDDB or other identifiers assist in the verification of text orother data within a database.

The content identification module 120 communicates content information124 to the broadcast data management module 122. The broadcast datamanagement module 122 uses the content information 124 to selectappropriate data 126 for inclusion in the broadcast. Some examples ofcontent information 124 communicated by the content identificationmodule 120 to the broadcast data management module 122 may includetitle, artist, cut number, spot, client, advertisement identificationsuch as Ad-ID, or Industry Standard Coding Identification (ISCI) asissued by the American Association of Advertising Agencies.

Further, it is not necessary to have a one-to-one correlation betweenthe content information 124 and the data selected for broadcast. It maybe desirable to communicate information about content to an algorithmthat then determines appropriate data for broadcasting over thesubcarrier frequency. For example, for a given artist, the algorithm maychoose to broadcast information about products from similar artists orother products by the given artist. Alternatively, the algorithm may usethe program information to select an advertisement campaign from adatabase of currently active advertisement campaigns. The algorithm mayincorporate routines for randomly selecting the broadcast data 126.

The broadcast data management module 122 may provide broadcast data 126without receiving content information from the content identificationmodule 120. This is particularly useful for emergency alert or trafficinformation. The broadcast data management module 122 may send alerts tothe full network of broadcast systems, or to localized broadcastssystems, depending on the nature of the warning or message. Thebroadcast data management module 122 may also initiate transmission ofbroadcast data 126 as part of an advertisement campaign.

The broadcast data management module 122 typically communicates with anevent database 128 to track the content information 124 and thebroadcast data 126. The event database 128 may include information suchas a broadcast event identifier, descriptive information about thebroadcast event, time that the broadcast occurred, or the station thattransmitted the broadcast. The broadcast event identifier provides asimple way of matching user responses with broadcast events.

In addition to the event database 128, the broadcast data managementmodule 122 may also communicate supplemental information to aid inidentifying a broadcast event. For example, one content identificationmodule 120 may identify a broadcast event by album and cut number.Another content identification module 120 may identify a broadcast eventby artist and title. Yet another content identification module 120 mayidentify a broadcast event by the record label. Providing supplementaldatabase information allows the normalization of various formats ofcontent information 124 into a standard format.

In one embodiment, the broadcast data management module 122 uses acontent database 134 to store information about known content. Thecontent database may include information such as artist, album, label,year, track titles, composer, availability, popularity, amount of airtime, or digital storage locations. A new entry may be created in realtime for items not listed in the database.

The broadcast data management module 122 may provide a graphical userinterface, a command line interface, or other mechanisms for controllingthe flow of data to the database. FIG. 3 shows an exemplary graphicaluser interface. As illustrated, the broadcast data management module 122may provide controls 135 for input and output ports, controls 136 fordata parsing, controls 139 for modifying or injecting various elementsof the RDS data stream such as PS or PTY, or controls 137 for data typefiltering. Events may be stored in the event database 128 for use with areporting server or fulfillment server, as well as being displayed 138in the user interface.

In one embodiment, the broadcast data management module 122 operates inthe same location as the automation software. In another embodiment, theautomation software communicates with the broadcast data managementmodule 122 over a network. The automation software may transmit, forexample, SOAP/XML (Simple Object Access Protocol/Extensible MarkupLanguage) data packets to a remote server. The server, running broadcastdata management module 122, would then provide, for example, a broadcastevent identifier in UECP (Universal Encoder Communication Protocol)compliant format to the IP port of an encoder.

Returning to FIG. 2, the broadcast data 126 may include a uniqueidentifier that corresponds to a broadcast event as communicated by thecontent information 124. The broadcast data management module 122generates the unique identifier, which, for example, may be random, ormay be based in part on time of creation or type of broadcast event. Inone embodiment, the unique identifier includes elements from the RDSstandard, such as the PI code. The broadcast data 126, including theunique identifier, is then provided to a subcarrier data encoder 130.The subcarrier data encoder 130 prepares the data for broadcast using abroadcast system 132. The broadcast system 132 may synchronize theencoded broadcast data 126 with information from the contentidentification module 120.

In one embodiment, the subcarrier data encoder 130 conforms to the RDSstandard. In another embodiment, the subcarrier data encoder 130conforms to the DARC standard. In yet another embodiment, the subcarrierdata encoder 130 conforms to the DAB (Digital Audio Broadcasting)standard. Other ways of encoding the data are also feasible. Many of theexemplary embodiments disclosed herein use the RDS standard for ease ofdescription. It is to be understood, however, that other types of datacommunication, including television, digital radio, satellite, orstreaming content, are also within the scope of the disclosure.

As an example of a data protocol for encoding the broadcast data 126,the subcarrier data encoder 130 may use the RDS standard. The RDSstandard generally defines the format for transmission of data. Thestandard also includes the capability for customization of broadcastpackets for a particular application using Open Data Applications,although Open Data Applications are not explicitly defined by thestandard.

The RDS standard uses groups that are 104 bits long to communicate datato a receiver. The format of each group of 104 bits is defined by 5 ofthose bits. These 5 bits are capable of identifying 32 different typesof groups. The groups of 104 bits are typically partitioned into 4blocks of 26 bits each. The group type may define in part the format forthe blocks.

The first block contains the program identification (“PI”) code, and isnot affected by the group type. The program identification codes providethe source of the broadcast. The program identification code may includeinformation about the country, program type in terms of area coverage,or a program reference number. In the United States, the programidentification codes are calculated using station call letters, and thecoverage area codes are not used.

FIG. 4 illustrates an example of a type 3A group 140 as defined by theRDS standard. Using the format of group type 3A 140, the subcarrier dataencoder 130 can convey information to a receiver about Open DataApplications carried on a particular transmission and in which groupsthey will be found. The 5-bit group type 142 includes 4 type bits and aversion bit. In the illustrated example, the 4 type bits “0011”represents group type 3, and the version bit “0” represents version A.Hence, a group having a 5-bit group type of “00110” is referred to asgroup type 3A.

The group type 3A 140 includes a five-bit Application Group type code144. The 5-bit Application Group type code 144 includes 4 type bits anda version bit. The Application Group type code 144 indicates the grouptype used, in the particular transmission, to carry the specified OpenData Application. For example, an Application Group type code of “10110”indicates that the broadcast data 126 will be located in group type 11A.The receiver would then look for and decode the 11A groups to extractthe broadcast data 126.

The group type 3A 140 also includes a 16-bit Application IdentificationCode (“AID”) 146. The subcarrier data encoder 130 uses the ApplicationIdentification Code 146 to identify the transmitted data as containingbroadcast data 126. Thus, a receiver can monitor the ApplicationIdentifier Code 146 to determine when a group contains the broadcastdata 126.

The subcarrier data encoder 130 may use the block 3 data bits when thebits are non-zero. This allows a total of 53 bits for data. The 16 bitscan precede or follow the 37 bits. If the data can fit within the 16bits, then the 3A group does not “point” to another data group. All ofthe data is contained within the one group. This makes more efficientuse of the bandwidth.

FIG. 5 illustrates the format for an ODA group 150. A group type code152 of the ODA group 150 is associated with a corresponding ApplicationGroup type code 142 (FIG. 4) from a group type 3A 140. As illustrated,there are 5 data bits 154 available in block 2, 16 data bits 156available in block 3, and 16 data bits 158 available in block 4. Inaddition, if the 16 data bits 148 of block 3 of the corresponding grouptype 3A are non-zero, they can be used as additional data bits.

FIG. 6 shows an example of a group type 3A 160, such as the one shown inFIG. 4, used with a corresponding group type 11A 162, such as the oneshown in FIG. 5.

The broadcast data 126 may be transmitted one or more times. In apreferred embodiment, the broadcast data 126 is periodically repeated toallow users tuning in after the start of the broadcast event the abilityto receive the broadcast data 126. For example, transmitting the dataonce a second allows users to capture the broadcast data 126 withoutusing excessive amounts of bandwidth. Further, the contentidentification module 120 may be synchronized with the broadcast toprovide a “pre announce” function for upcoming broadcast events.

A radio station can broadcast data regarding the current song oradvertisement that is playing, such as the song title, artist ormanufacturer, album name or product, and year the song was recorded. Theradio station can also broadcast information providing a location wherethe song, editorial news broadcast, collection of songs, or otherprogram material can be downloaded or purchased, and the purchase pricefor the song.

Additionally, the broadcast data 126 may include instructions, anInternet address, alias or phone number for the location of a look uptable used to reference the location of downloadable audio. Once thecontent data source is identified, the information is also stored in a“look up” table. The codes representing “cut numbers”, or text songinformation such as artist and song title, are referenced against theinternal look up table to determine if the song is available fordownload from a content provider such as a distributor, music publisheror record company. Once determination has been made regardingavailability of the requested content, the broadcast data 126 isformatted so that the RDS data contains the directions to or address of,the look up table which points to the download location and/or filename.

The capabilities of the RDS Open data Application allow for theinclusion of an Internet IP address and directory location for routingthe request for purchase from a user to the appropriate download sitesuch as a publisher, record company or news organization. In anotherembodiment, the broadcast data 126 contains a reference code forretrieving the download location from a lookup table. The results ofquerying the look up table may be returned to a location such as awebsite or wireless phone as declared by the user when they establishedtheir service. This information is stored in a consumer database. Theresults may then be forwarded to the selected location such as awebsite, email address or cell phone number as a text message for reviewand redemption.

Broadcast Data Reception

FIG. 7 illustrates an example of a broadcast receiver 200. A radiofrequency (RF) demodulator 202 receives an RF signal 262 and separatesthe subcarrier signal from the main signal. The broadcast receiver 200typically provides appropriate circuitry 208 for amplifying video oraudio 228 from the main signal before presentation to the user 218,although it may be feasible to only use the subcarrier signal in someapplications.

The broadcast receiver 200 provides the subcarrier signal to asubcarrier data extraction module 204. In one embodiment, the subcarriersignal conforms to the RDS standard.

In the illustrated embodiment, the data extraction module 204 uses a DSP(Digital Signal Processor) and a microcontroller to extract data fromthe RDS channel. The firmware code may reside in the DSP, themicrocontroller, or baseband or a combination of the modules. The codereceives and processes service data transported via a subcarrier signalto the receiver. The code may also contain an algorithm for receiving avariable allowing the receipt of a series of different serviceidentifiers.

Activation of data processing is engaged by receipt of a serviceidentifier or variable. This service identifier may reside in either theDSP, MC or baseband chip but may be found in any or all of the chips.The same identifier or variable is transported in the subcarrier signalin order to activate the process of decoding broadcast event identifiersand storing them in cache.

FIG. 8 is a flow-chart diagram for extracting RDS data from thesubcarrier channel. At step 300, a received RDS signal is synchronized.After the signal is synchronized, the extraction module 204 candetermine when a new block is received. The block data is decoded atstep 302. The first block in a group contains the programidentification. The extraction of the program identification from thefirst block (not shown) also occurs at step 302. The extraction module204 checks for receipt of the second block at step 304. The extractionmodule checks to see if the group type code is 3A at step 306 if thesecond block was received at step 304. The extraction module 204 storesthe Application Group type code at step 308 if a group type 3A wasreceived. Otherwise, the extraction module 204 checks for a match of thegroup type code with a previously received Application Group type codeat step 318.

If the Application Group type code was received at step 308, theextraction module 204 decodes the third and fourth blocks at steps 310and 312, respectively. The extraction module 204, at step 314, comparesthe Application Identification code from block four with a predeterminedApplication Identification code associated with the event informationextraction. If the Application Identification code is a match, theApplication Group type code from block two is stored in memory at step316.

Returning to step 318, a match of the group type code with a previouslyreceived Application Group type code indicates that the group containsbroadcast data 126. The extraction module 204 extracts five bits fromblock 2 at step 320, 16 bits from block 3 at step 322, and 16 bits fromblock 4 at step 324. The resulting 37 bits are placed into memory atstep 326. In addition to the 37 bits representing broadcast data 126,the extraction module 204 may place other identifying information suchas the program service name (“PS”), program type (“PTY”), programidentifier (“PI”), traffic program (“TP”), traffic announcement (“TA”),or time the group was broadcast into memory.

The RDS standard includes support for error detection. The broadcastreceiver 200 may apply an additional layer of error detection/correctionby using, for example, double buffering. FIG. 9 illustrates aflow-diagram for performing double buffering. In this example, the samevalue is read in two or more consecutive ODA groups before being enteredinto memory. This technique does not rely on RDS error correctionschemes, which can introduce errors. When synchronization is lost or thetuning frequency changes, the buffers may be cleared. Double bufferingmay also be used for other RDS features such as program identifier,program type, traffic program or traffic announcement. Multiple groupssuch as program service or radiotext can also be double buffered withthe addition of a status flag that tells when the segments of data arethrough the double buffer. Once the segments are double buffered, theentire data element is stored.

As shown in FIG. 9, the first data is read at step 340. The first datais stored in location X at step 342. The second data is read at step344. The second data is stored at location Y at step 346. If the firstdata in location X is the same as the second data in location Y at step348, then the data is stored at step 350.

In some cases, the memory may contain previously received informationabout the broadcast data 126. For example, as explained previously, oneembodiment broadcasts event data every second. Storing each of therepetitive broadcasts into memory results in inefficient use of thestorage resources.

Even if the extraction module 204 stores only unique broadcast eventdata into memory, at some point the memory limits will eventually bereached. The extraction module 204 may advantageously purge old data orshort term data from memory to make room for new data.

Keeping the extracted data in memory allows a user to review thebroadcast event data even after the broadcast event is finished.Further, the memory allows a user to select from multiple optionsrelating to a broadcast.

For example, a radio station conducting a survey may send one code for a“yes” response, and a second code for a “no” response. In anotherembodiment, a single broadcast event identifier may include coding toindicate that a yes/no question has been posed. For example, 4 bits ofthe broadcast event identifier could identify the category of thebroadcast event, leaving the remaining 33 bits to uniquely identify theevent. When the broadcast receiver 200 recognizes that the 4 bitscorrespond to a broadcast event category of a yes/no question, thebroadcast receiver can then display the yes/no options to the user.

A user responding to the broadcast event causes the generation of areceiver outbound data packet. The receiver outbound data packet maycontain, for example, RDS fields corresponding to broadcast stationidentification, a broadcast event identifier, a user identifier, or atime stamp. When responding to a yes/no question, the broadcast receiver200 could change one or more bits of the broadcast event identifier toindicate the selection by the user from the available options. In thiscase, the broadcast event identifier contained in the receiver outbounddata packet may not be identical to the broadcast event identifierreceived by the broadcast receiver 200. Alternatively, the receiveroutbound data packet could include supplemental information indicatingwhich selection the user chose from the available options.

In another embodiment, the radio station may pose a question withmultiple choices available as the answer. The user can scroll throughthe choices to select the desired answer. Similarly, the radio stationmay broadcast multiple album titles by an artist currently on air. Thelistener can then select and purchase one or more of the various titles.In another embodiment, the user may express a “vote” by selecting achoice.

The broadcast data 126 may include supplemental text to accompany abroadcast event identifier. The text may be sent as part of the ODAgroup, or it may be sent using predefined RDS standards, such as theradiotext group type 2B. The broadcast receiver may also store thesupplemental text in memory for display to the user.

User Response

Returning to FIG. 7, the broadcast receiver 200 may include a userinterface. The user interface may include a display 208 and a responsemechanism 210. In one embodiment, the display 208 receives display datafrom the subcarrier data extraction module 204. The display data 208 caninclude information such as the program service name and program type,or it can include radio text information or messages displaying purchaseor response options. The display 208 may show several lines of text atonce, or may display a single line. The user interface may also includemechanisms for the user to scroll through several lines, displaying oneor more lines at a time. For example, the user interface may includebuttons that allow a user to scroll up and down between lines of text.Further, the user interface may provide for scrolling horizontallyacross the display. This can occur automatically or may also becontrolled through the user interface.

The user interface may include buttons, a touch pad, a keypad, ajoystick, a mouse, speech recognition, or other mechanisms for enteringa response. User responses may include, for example, selecting an itemfrom the display, responding to a broadcast question, tuning into adifferent broadcast signal, turning a device on or off, or adjusting thebroadcast signal volume. In one embodiment, the user is able to purchasea product by pressing a single button. In one embodiment, a response tothe broadcast data 126 is sent without user involvement. Thisadvantageously provides a mechanism for tracking demographic data.

The broadcast receiver 200 generates a response data packetcorresponding to the user response. The response data packet includesinformation such as the program identifier, the broadcast eventidentifier, the location of the stored broadcast events or a useridentifier. The response data packet may include other information suchas the time of the user response, time of the event broadcast or thetype of the user response (e.g., order, tune into different frequency,turn off broadcast receiver, or which button was pressed). Including theevent broadcast time in the response data packet may help reduce errorsin processing the response data packet.

In one embodiment, a broadcast data packet 126 provides the destinationof the response data packet. In one embodiment, the destination may betransmitted in a separate ODA Group from the broadcast program relateddata. Using three consecutive transmissions of this separate ODA Groupwould allow the transmission of a destination address of up to 12alphanumeric characters along with an identification of the addressformat (e.g., IP address or telephone number) The destination may bestored in non-volatile memory, such as flash memory. The broadcastreceiver can then access the response data packet destination even afterthe power has been turned off. In another embodiment, the destination isperiodically transmitted, and the broadcast receiver keeps userresponses in a queue until the destination is received. The destinationmay be received separately from broadcast event data.

The destination may be combined or parsed into separate entities. Forexample, one entity may include the IP address of a server, and a secondentity may include a location of a file or script on that server. Thisallows the IP address and file location to be updated independently. TheIP address may be stored as a numeric identifier (typically four bytes)or as an alias that can be much larger. Thus, an updated server locationcan be transmitted by sending as few as four bytes as part of an updateblock. Similarly, the file location may also be updated with thetransmission of an update block.

The update block may have its own ODA format, or it may be transmittedusing the same ODA format as the broadcast event identifiers. Asdiscussed previously, one or more bits may be used to specify thecategory of the event. Thus, four bits could be used to identify thecategory as an update block, and the remaining bits could be used totransmit the IP address or file location. Compression such as Huffmancoding may be used to transmit the data. The data may be further limitedto specific characters, such as the 26 letters of the English alphabetor special characters such as “/”, “?”, or “.”.

The response data packet may be formatted in a variety of ways. Someexample formats include Bluetooth, SOAP/XML, SMS (Short MessageService), MMS (Multimedia Messaging Service), GPRS (General Packet RadioService), or Mobile Control Channel.

The user identifier may be uniquely assigned to the broadcast receiveror determined from another source. For example, a radio receiver in anautomobile may communicate via an automobile communications bus, such asthe MOST (Media Oriented Systems Transport) bus, to determineidentifying information such as a vehicle identification number.Alternatively, the user identifier may be entered using the userinterface. The user identifier may correspond to a credit card accountor an identifier for some other payment system such as PayPal. The useridentifier may also be determined from a communications interface 212.For example, the communications interface 212 may have the ability tocommunicate with a GSM (Global System for Mobile) wireless telephone anddetermine the telephone number from the Subscriber Identity Module(SIM). Certain hardware devices come with embedded identifiers such as aMAC address which may be queried and used as an identifier. GeneralPacket Radio Service (GPRS) offers a continual connection through awireless IP network for high speed data transmission. Thus, a datapacket may be directed to an IP address using GPRS. The service providesits own IP address that may serve as an identifier. Alternatively, thecommunications interface 212 may include the ability to accept interfacecards, such as a flash memory card, a credit card or credit card accountinformation for storage within a SIM or other storage module. The useridentifier could be, for example, a user name, a telephone number, anidentifier from a third party, an electronic serial number (ESN), awireless identification number (WIN), or a proprietary identifier.

Another embodiment uses the BlueTooth wireless specification with thePhone Access Profile (PAP) protocol stack specification. The PAPspecification allows the use of a mobile phone or embedded phone inconjunction with a terminal device such as a cordless handset or car-kitinstalled in a car. The BlueTooth link provides wireless communicationfor remotely controlling the telephone by the terminal device. A PINcode may be used upon first use for initializing communication betweenthe two devices. The PAP provides access to the subscriber numberinformation, as well as other features such as call forwarding, callbarring, or call waiting.

The broadcast receiver 200 may use a communications interface 212 forcommunicating the user response or other data to the data managementmodule 110, and for receiving incoming data. The user response may becommunicated at the time of the user response, or held in a staging areafor later communication. The communications interface may provideadjustments for available bandwidth by transmitting the user responsesas a single packet or a plurality of smaller packets. The amount ofinformation pertaining to the user responses and transmitted over thecommunications interface may also be adjusted to the availablebandwidth.

The communications interface 212 may use a variety of technologies, suchas wireless technology, data storage mediums, or electronic connections.For example, a user response may cause the broadcast receiver 200 toinitiate a communication using BLUETOOTH™ wireless technology withanother device such as a wireless telephone. The broadcast receivercommunicates the user response to the wireless telephone, which thencommunicates the user response to the data management module 110 (shownin FIG. 1). Other examples of technology for communicating the userresponse include code division multiple access (CDMA), time divisionmultiple access (TDMA), Cellular Digital Packet Data (CDPD),transmission control protocol internet protocol (TCP/IP), modem, IEEE802.11 wireless networks, short message service (SMS), MultimediaMessaging Service (MMS), general packet radio service (GPRS), or mobilecontrol channel.

Alternatively, a port such as a 9-pin serial port, a USB port, Firewire,a parallel port or other port may provide connectivity between thebroadcast receiver and other devices. Another embodiment uses flash cardtechnology or other removable storage media. The removable storage mediaallows a user that does not have a connection to a wireless or landlinenetwork to store responses for later use. The ports or removable storagemedia provide connection to devices such as a personal computer, digitalcamera, wireless phone, personal computing device, kiosk, digitalstorage system or personal digital assistant.

In one embodiment, the communication interface 212 polls a wirelessnetwork until a good connection is obtained, at which point theselection data is transferred for completion of the transaction. Incases where the user cannot obtain a good connection or the user doesnot have a wireless account, the storage media can later be removed bythe user and inserted into a personal computer. The personal computerthen communicates the responses stored on the storage media to the datamanagement module 110.

FIG. 7 illustrates an exemplary embodiment where the receiver outbounddata packet is transmitted over a communications channel 256. Theoutbound data packet may include, for example, the PI, event identifier,destination for the data packet, user identifier, or time stamp. In theillustrated embodiment, the outbound data packet is communicated to adatabase 250 for further processing. The database 250 furthercommunicates, using, for example, an internet connection, with acomputer 260. The computer 260 may further communicate using a networkconnection 258 with an authentication and billing system 252.

Using the disclosed embodiments, the user can respond to a livebroadcast radio advertisement to qualify for discounts, premiums orother sponsor-offered rewards. This system can also be applied to pledgedrives employed by public radio stations, allowing listeners to pledgemoney while driving or listening to a portable radio. The system canalso be used for listener polls where the broadcaster can obtain quickresponses from listeners to new music, speech content or generalquestions such as a talk show format. The system can also be used forshopper incentive programs where a listener responds to an on-air event,data is passed to a third party database (i.e. a database maintained bya retail or grocery store), and the listener uses a club card to claim adiscount or buy a product at the third party store. For example, aspecial premium may be provided to a listener because the listener is aclub card holder that responded to the on-air event.

The user can also receive offers or hyperlinks posted on a personal website presenting premiums such as discounted tickets (to events for theartists or writers for which they purchased content), suggestions ofpurchase for related artists or music genres, record company clubofferings, or other premiums. Associated books, magazine articles,merchandise and event information can also be posted for the user topurchase. Hyperlinks can also be present for content not available onthe radio but provided either through partnerships with existing digitalcontent providers or content owners who have made direct arrangementsfor digital distribution through the data management module 110 orpartner web site.

In one embodiment, a user's credit card number is stored on a SIM cardsuch as is used in GSM telephones. This allows a user to pay for an itemby pressing a button on the telephone without entering the credit cardnumber. In another embodiment where the credit card number is notstored, the user is prompted to enter the credit card number on the GSMtelephone or other wireless communications device. Alternatively, theuser may pay, for example, by PayPal or a similar service, or the usermay elect to have the purchases included in the wireless bill orinternet service provider bill.

In one embodiment, the user receives delivery of purchased material overa wireless communication. Thus, a user can receive the purchasedmaterial while traveling. In one embodiment, the system also providesdelayed delivery, when, for example: the user so chooses; the user doesnot have a wireless account; or the user cannot obtain a good signalwith a wireless connection for transmission. In another embodiment, thepurchased material is delivered to a location remote from the broadcastreceiver. For example, the user may purchase material while listening tothe radio, and that material may automatically be delivered to a homecomputer.

Alternatively, a user may, for example, press a button requesting moreinformation about the broadcast event. Upon receipt of the additionalinformation, the user may then make a decision regarding a purchase. Theadditional information may be reviewed, for example, on a website or ona wireless telephone.

In another embodiment, the material is delivered to a server for latercommunication to the broadcast receiver 200. For example, a user drivingan automobile may request delivery of music to a wireless home network,such as a network conforming to IEEE 802.11. Then, upon parking theautomobile within communication range of the wireless network, therequested music is transferred to the broadcast receiver 200 in theautomobile. The broadcast receiver may contain a storage module 214 forstoring delivered media content. The storage module 214 may also be usedto store broadcast information such as the PI or event identifier suchas a numeric event identifier (NEI). The storage module 214 may use, forexample, flash memory, hard drive, CD-RW, DVD-RW, DVD+RW, or otherstorage mechanisms.

In another embodiment, the user receives a link to a download locationon the internet. The link may be communicated to the broadcast receiveror to another location, such as an email address, that is accessible tothe user. A user may also request that the material be delivered usingtraditional parcel mailing services.

As many users may not have a broadcast receiver 200 that includes themodules for decoding the broadcast data 126, the broadcast data 126 mayadvantageously be transmitted to a server for access over a network.Thus, a user listening to a broadcast may view, for example, a web pagethat displays choices representative of the choices shown on the display208 of the broadcast receiver 200. A log of broadcast events may also beavailable on the web page.

The web page may also present items such as time or airing, artists,titles, pricing or advertisements with links to other pages. Forexample, an artist may be linked to a page that provides tourinformation or a title may provide a link for downloading a digitalversion of a song or purchasing a CD. Advertisements may be linked witha page that provides discounts, samples, or product purchase capability.

In order to protect the purchased content from piracy, variousaccess-rights controls and copy-protections can be provided. In oneembodiment, the user purchases a license to store a single copy ofcontent to a CD or flash card. Additional licenses can be purchasedthrough the data management module 102 without requiring additionaldownloads. File formats such as WMA (Windows Media Audio) from Microsoftprovide built-in copy protection and are supported by many recordlabels.

User Services

FIG. 10 shows a sign-up interface 502 for entering user information. Auser may sign up to participate in the program by providing the neededidentification information. For example, the user may enter the name,telephone number, address, age, marital status, gender, household size,income, interests, user name, contact, or connection information. FIG.11 shows an interface 504 for selecting user interests. In oneembodiment, the user account is associated with an internet serviceprovider (ISP) account or wireless carrier account.

The user may request notification of specified events, such as concertticket availability, contests, songs of interest being aired, or otherevents of interest to the user. The notification may be sent, forexample, by email, instant messaging, SMS or MMS. The user may forwardnotifications to friends or acquaintances. The user may be rewarded withsome form of premium for forwarding the notification to others. The usermay also be rewarded with a premium for each time an acquaintanceforwards the message on to another user. In one embodiment, themessaging is tracked to determine the awards.

The user can set up a purchasing account to allow for the purchase ofproducts. The purchasing account may be established through, forexample, a wireless carrier, an internet service provider, a radiostation website, a retail store kiosk or other third party billingservice. The user may be provided with an End User License Agreement inorder to use the services.

The sign-up interface may be customized for use with third parties. Forexample, an internet service provider could offer interactive radioservices to its users by presenting the sign-up screen as part of thethird party web-site.

FIG. 12 shows an interface 506 for customizing a ticket purchase programfor a user. As shown, a user may indicate a favorite music venue.Information such as city or zip code may be used to determine the venuesthat participate in the program within a given area. The user may selecta favorite seating section and favorite artists. Other options mayinclude the number of seats, payment method or notification method. Theuser may pay, for example, by credit card or PayPal or other service, orthe user may elect to have the purchases included in the wireless billor internet service provider bill. This notification method selectionallows the user to be notified when tickets become available forperformances that the user may be interested in. For example, the usermay be notified by wireless SMS, text messaging, email, or on theinternet. A user may be provided with the option to purchase ticketswhen they become available.

The user may elect to participate in usage tracking regarding theirresponse to on-air content for the collection of demographic data. Theuser may receive incentives such as frequent flyer awards or free musicfor using the system for allowing their usage to be tracked. A user mayelect to receive discounts, product samples, trial programs and prizesrelated to the selected user interests.

A user may also track an account or summary of user responses by using,for example, a pager, website or wireless telephone. A use may reviewsongs or advertisement events and message responses through the use ofwireless technology such as SMS return codes. In one embodiment, theuser accesses a web interface that provides information such as the day,time, artist, song title or advertisement event. The web interface mayprovide links for information such as tour information, purchasingoptions, download locations. Advertisements may be linked with a pagethat provides discounts, samples, or product purchase capability.

Events may be indexed with the ability to scroll forward or backwards asappropriate or be searchable through the use of input fields. In oneembodiment the events are indexed by the broadcast identifier. Inanother embodiment the events are indexed by time. The events mayfurther be indexed, for example, by hour blocks to more quickly reviewthe events. Thus, a user wishing to review events that occurred between7:40 and 7:50 may either scroll forward from 7:00 or backwards from8:00.

Data Management

The data management module 110 communicates with the event database 128the content database 134, a user database, and a response database. Theuser response packets can be monitored by the data management module110. The data collected through “data mining” of user responses can besold to companies interested in tracking demographic information andmusic sales such as record companies and trade publications. Thetracking of user responses may be done in a way to keep the useranonymous.

FIG. 13 shows a user interface 508 for the data management module 110,which allows for demographic tracking using a variety of parameters. Theuser interface may be tailored to specific user types, such asbroadcasters, advertisers, or content providers.

The broadcaster may be interested in real-time reporting for one or moreradio stations located in one or more areas. The broadcaster may selectthe areas and radio stations of interest. Other options may includesearching by broadcast event, advertising campaign, artist, or othertypes of data such as those stored in the event database 128, thecontent database 134, the user database or response database.

The advertising campaign is identified, for example, by an Ad-ID or ISCIcode as defined by the American Association of Advertising Agencies(AAAA) and the Association of National Advertisers (ANA). Ad-IDgenerates unique codes for advertisement identification, scheduling,placement, billing and verification purposes. Ad-ID is an alphanumericcode that is backwards compatible with the ISCI code. The datamanagement module 110 may communicate with the AAAA database to identifyadvertisement campaigns. In one embodiment, the broadcast datapreparation module uses the Ad-ID for generation of the broadcast eventidentifier.

As shown in FIG. 14, the broadcaster may generate reports 510 from theselected search criteria. Real time reports track the broadcaster'saudience by parameters such as gender, age, location, time, orredemption occurrence.

Similarly, an advertiser or content provider may desire to track useractivity. For example, record companies and publishers can track numberof plays or responses by market or markets for their products. They cantrack trends and monitor interactive responses.

Order Fulfillment

Requested content can be sent directly to the broadcast receiver 200using wireless communications. Requested content can also be directed toa personal web page assigned to the user. Content may also be directedto a wireless device. The user can access the account over the Internetor via a wireless device, and the user can download purchased content toa personal computer or wireless device.

The data management module 110 matches the information sent from theuser response data packet with information in the event database. Thedata management module 110 verifies the customer information anddetermines whether the customer account can be debited for the cost ofthe order. The data management module 110 then provides an approvalsignal indicating whether the purchase was approved.

FIG. 16 shows an exemplary interface 512 for displaying a playlist to auser.

FIG. 17 illustrates a redemption screen 514. Users may establish singleor multiple redemption points upon establishment of service. These mightinclude a third party website, radio station website, wireless providerwebsite, wireless phone, or other method of reviewing selections made byresponding to on-air content.

One expression of redemption provides the user a secure web environmentwhere all selections are presented as interne hyperlinks that whenclicked upon, directs the user to a content source where the pricing,terms and delivery methods are available. In addition, relatedadvertising, more associated information and offers may also be present.Users may gain points such as music points or frequent flyer miles forredemption activities.

PRESENTLY PREFERRED EMBODIMENT

FIG. 15 illustrates a flow diagram of a presently preferred embodimentof a broadcast response system. As shown, radio automation software or aCD playback system 442 communicates content information 440 to abroadcast management module 444. The broadcast management module 444compares the content information 440 with entries in the contentdatabase 482. The content information 440 is associated with a numericevent identifier (NEI). An outbound UECP packet 445 comprising, forexample, AID, PI, NEI, RT, receiver outbound destination and PTYelements, is communicated to an RDS encoder 448. Similar information iscommunicated over a communications link 466 to an event database 484.The outbound UECP data packet 445 is formatted for use with the RDSsubcarrier 470, and a baseband program with subcarriers 472 istransmitted by a radio station transmission system 446.

The transmitted RF signal 462 is received by an RDS-enabled radio 400,similar to the broadcast receiver 200 illustrated in FIG. 7. The radioincludes a display 410 and a user interface 416. When a user responds tothe broadcast, a receiver outbound data packet 412 is communicated to acommunications device 449. The communications device 449 may transmitthe receiver outbound data packet 412 using a wireless carrier network447 to the stored outbound destination. Optionally, the radio maycommunicate with, for example, a personal computer 441. The wirelessnetwork 447 also allows for data to be uploaded to the radio 400. Thus,a user may order a digital song and have it uploaded to the radio.Optionally, the data uploaded to the radio could update the automotivesoftware. In one exemplary embodiment, the receiver outbound data packetis communicated to a system management module 450. The system managementmodule 450 is in communication with a consumer database 481, a responsedatabase 483, a content database 482, an event database 484, a purchasedatabase 486, and an activity audit database 485. The event data anduser responses may also be monitored in real time using a monitoringmodule 470. The system management module 450 may also be incommunication with a fulfillment module 454 or a billing module 452. Asis apparent from FIG. 15, many of these modules are interconnected or incommunication with each other.

SUMMARY

One of ordinary skill in the art will recognize that there are variousforms of media that can be broadcast. Where a specific type of media isdescribed in the embodiments herein, it is for demonstration purposesonly and the embodiments should not be limited in that regard. Someexamples of the various types of media can include music, speech, textor video.

It should be understood that data transmission standards other than RDS,RBDS, DARC and DAB are also operable with the embodiments disclosedherein, and the scope of the disclosure should not be limited to thosestandards.

The system may include one or more of the following features: allow theuser to establishes a “creative content” direct purchasing account orwith a wireless carrier or other approved billing partner; provide apersonal URL (web address) for the user to monitor account activity,enable or disable software downloads, display premiums offered bysponsors, manage and track responses using a broadcast receiver or apersonal computer, makes routing choice between the broadcast receiveror the web account for content, make selection of compression type(e.g., WMA, MP3 (MPEG-1 Audio Layer 3), RA (Real Audio), Liquid Audio),opt-in to usage tracking programs where demographic data is collected bypermission from user, opt-in to rewards and redemption programs whereusers can for example, accumulate frequent flyer miles for purchases andparticipation, receive automatic notification of tickets for eventswhere users input a zip code which returns the concert venues in thatlocation, purchase tickets, or select favorite artist, favorite sectionin the venue and payment method.

RDS/RDS is an FM-only transmission system but one of ordinary skill inthe art will recognize that data can be included with other broadcastservices. For example, use of dual tuners in a radio allows the RDS/RDSdata to be passed down the FM subcarrier in association with an AMstation. When a user response occurs, the broadcast receiver 200references the data captured from the FM signal and returns it in theresponse data packet.

Digital Audio Broadcasting (DAB), which includes flexible, open-source,data transmission functions along with the audio signal. Systems foradapting digital audio and data transmission to the current allocationof AM and FM stations using a technique known as In Band On Channel(IBOC) are known. IBOC includes an ancillary data stream in thebroadcast signal to be used by the station for whatever purposes theysee fit. The ancillary data stream signal can be used to carry broadcastdata 126 information.

Other developing radio systems also include a data path that can be usedto send the information to successfully allow the acquisition of musicor other material being broadcast. Satellite DAB providers, such as XMSatellite and Sirius Satellite Radio, have access to the audio andancillary data signals being sent to compatible receivers.

As other audio services develop, the capability to transmitcomplimentary, simultaneous data can be used with no significant changein the overall system.

Wireless technology and the related developments in high-speed Internetaccess using systems such as BlueTooth or other wireless networktechnology allows faster downloads of the desired material by takingadvantage of the newer, faster technology.

NTSC (National Television System Committee), PAL (Phase AlternatingLine) and other technologies employed to transmit television signalsaround the world allow for similar capabilities in transmittingsubcarrier data within the carrier signal.

The specific embodiments described herein are merely illustrative.Although described in terms of certain preferred embodiments, otherembodiments that are apparent to those of ordinary skill in the art,including embodiments which do not provide all of the benefits andfeatures set forth herein, are also within the scope of this invention.

Accordingly, it is to be understood that the patent rights arisinghereunder are not to be limited to the specific embodiments or methodsdescribed in this specification or illustrated in the drawings, butextend to other arrangements, technology, and methods, now existing orhereinafter arising, which are suitable or sufficient for achieving thepurposes and advantages hereof.
